A perfect ACCESSORY to add to the TRAC TIRE JACK.......Introducing the TRAC TIRE JACK Roller Accessory Plate......By ADDING the Plate to the tool it allows for an easier alignment of the holes of the wheel to the studs on the hub. If you thought the process was easy before, wait until you try this Roller Plate...Simply roll the wheel while it is on the tool for proper alignment. The recommended tire tread pattern is an all-terrain tread as a heavy mud terrain may get caught in the rollers. For the mud terrain or aggressive tread we recommend the top cradle that can be mounted to a motorcycle floor jack.
